Solution Overview

Problem

Existing road barriers lack an effective mechanism to prevent further movement of vehicles once impacted, particularly heavy vehicles like trucks or buses, necessitating improved control over vehicular transportation.

Innovation Solution

A rolling barrier system comprising barrier units with curved rods and upright segments that roll beneath the vehicle upon impact, utilizing sharp edges and sticking elements to embed into the vehicle and surface, converting kinetic energy into potential energy to halt the vehicle's movement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional road barriers are used to block vehicles, then road control and security are improved, but the barriers cannot effectively prevent further movement of heavy vehicles once impacted

Engineering Contradiction:
Improvevehicle immobilization effectivenessVSAvoidbarrier structure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The barrier unit is designed to transition from a static upright position to a dynamic rolling motion upon vehicle impact. The curved rod configuration enables the barrier to roll beneath the vehicle, converting the vehicle's forward momentum into rotational motion of the barrier, thereby effectively immobilizing heavy vehicles that would penetrate traditional static barriers

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The barrier unit incorporates curved rods instead of straight structural elements. This curvature is essential for enabling the rolling motion beneath the vehicle. The curved geometry allows the barrier to rotate smoothly under the vehicle's weight and momentum, creating an effective mechanical stop that prevents further vehicle movement

Inventive Principle:
Principle #14Spheroidality (Curvature)

2Reliability

If barrier units are designed to roll beneath vehicles to convert kinetic energy, then vehicle movement control is improved, but the mechanism complexity increases

Engineering Contradiction:
Improvekinetic energy conversion effectivenessVSAvoidrolling mechanism complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The barrier unit utilizes the vehicle's own kinetic energy and weight to activate and sustain the rolling motion. Once impacted, the vehicle's momentum automatically drives the barrier into rolling motion without requiring external power sources, actuators, or complex control systems. The design converts the harmful impact energy into useful mechanical work of rolling beneath the vehicle

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The barrier system is divided into multiple identical modular units, each comprising curved rods and sticking elements. These segmented units can be independently manufactured and assembled, simplifying the overall system complexity while maintaining effectiveness through the collective action of multiple rolling units beneath the vehicle

Inventive Principle:
Principle #1Segmentation

3Stability of the object's composition

If sticking elements are added to embed into the surface, then barrier stability is improved, but manufacturing complexity increases

Engineering Contradiction:
Improvebarrier unit stabilityVSAvoidmanufacturing simplicity
Core Design Contradiction:
Stability of the object's compositionVSEase of manufacture

Solution Approach 1:

The sticking elements are integrated directly into the curved rod structure during manufacturing, combining the structural support function and the anchoring function into a single unified component. This merging eliminates the need for separate anchoring mechanisms or additional assembly steps, maintaining manufacturing simplicity while ensuring barrier stability during and after the rolling operation

Inventive Principle:
Principle #5Merging (Combining)
